Abstract (en)
[origin: WO2022194553A1] The invention relates to a position-sensing device for a rotational angle sensor, to a rotational angle sensor having a position-sensing device of this type, and to a system having a rotational angle sensor of this kind. An exemplary embodiment of the position-sensing device comprises at least one stator, at least one rotor and an evaluation unit. The at least one rotor has a main body and at least one rotor blade extending radially outward from the main body. Between at least one first of the at least one rotor blade and the at least one stator, there is a first dielectric having a first permittivity. Between at least one second of the at least one rotor blade, or at least one free space adjoining the at least one first rotor blade in the circumferential direction of the rotor, and the at least one stator, there is a second dielectric having a second permittivity. The first permittivity and the second permittivity are different from each other. The evaluation unit is designed to sense if the at least one first rotor blade reaches, has reached or exceeds a predefined rotational position.
